There is a python-dns package available in EPEL5, but not in EPEL4. As far as I can see the only requirement for python-dns is Python 2.2 (http://www.dnspython.org/svn/dnspython/head/README), so could python-dns be built for EPEL4 as well?
Package Change Request ====================== Package Name: python-dns New Branches: EL-4 Owners: jcollie
cvs done.
Packages should now be available.
